What We Don't Like

Resident Audio is the rookie company in the audio engineering field, but with its poster child T4, they have high hopes. But can they compete with the veteran companies in the industry? Let’s see what T4 has to offer.


The T4’s design is sleek, sporting a black and silver body made of aluminum and acrylic. But we know looks aren’t everything. So what does this model come with? The main thing it boasts is that it requires no external power and no need for batteries, making it one of the first Thunderbolt audio interfaces to do so. It also includes a USB card with a T-Series driver.

Even though this is one of the more stylish audio interfaces, that doesn’t really matter when it comes to recording. This isn’t like a sports car that you get to flaunt around town — only you and any musicians you work with will possibly see the interface.

But the simplicity of the knobs and switches — an ON/OFF switch for phantom power and one knob for each channel’s gain — is a big plus for basic recording. Too many knobs can get confusing, especially if you’re a beginner at recording on your own.


This interface comes with four inputs that work with both XLR and quarter-inch lines. This also has four outputs, which is typical for an interface like this one. And having two headphone outputs is super convenient in theory. You’d think this would be perfect for engineering a recording session with another musician, but you’re not able to send an output signal to both headphones at the same time — it must be one or the other.

Preamps are always a good thing, and the T4 has those built-in. And, as it should, it has near-zero latency, meaning your recording and playback should be almost exactly on time.

The glaring issue is that the setup can cause you a lot of trouble. It requires that you first download a driver from the company’s website, and users report compatibility issues with both iOS and Windows. Additionally, your computer must accept a Thunderbolt 4 input, not 3 or 2.


In theory, this interface has all the features a home-recording musician would need. But when it comes to actually performing how you’d expect it to, it doesn’t. It’s a fully functioning audio interface, but the expectations you get at first glance are not met when you try to use it the way most musicians would use it.

When it comes to using the interface with your computer, it has to work seamlessly, and this one doesn’t always do that. Granted, it works for most users, but a handful of folks get frustrated with the initial setup, not to mention potential glitches experienced along the way.

A big let-down is that the two headphone jacks cannot accept outgoing signals at the same time. Being able to play back your song into two pairs of headphones at the same time is sometimes needed, and this interface won’t allow that.

The Rumble:

It’s a good looking interface that’s easy to use, and being able to record with four inputs is uncommon for an interface for this price. But the functionality of this device doesn’t quite live up to its external beauty.
